Cabling the Meter to a Host

The meter communicates with a host through an interface connector on the rear panel of the meter. First turn the meter off, then cable the meter to the host.

Getting Started With An Installation Test

After the meter has been cabled to a host and prepared to communicate with it via the RS-232 or IEEE-488 interface (as described above), test the system to verify that it is operational.

Installation Test for RS-232 Operations

The procedure below illustrates how the meter performs a computer interface command and, at the same time, confirms that the meter has been properly set up and cabled for remote operations:

1.Press the POWER button in to turn the meter on.

2.Verify that the computer interface parameters (e.g., baud, parity, etc.) are set correctly.

3.Turn the host on.

4.Send the meter the following command. *IDN? <CR>

5.Verify that the meter sends the following response FLUKE, 45, nnnnnnn, n.n Dn.n

=>

nnnnnnn is your meter’s serial number; n.n identifies the main software version; and Dn.n identifies the display software version. The RS-232 prompt => means that the command has been executed and the interface is ready to accept another command.

Installation Test for IEEE-488 Operations

The procedure below illustrates how the meter performs a computer interface command and, at the same time, confirms that the meter has been properly set up and cabled for IEEE-488 operations:

1.Press the POWER button in to turn the meter on.

2.Verify that the meter’s IEEE-488 address is set correctly.

3.Turn on the host or controller.

4.Enter the following at the host:

Note

This is a program as entered from a Fluke 1722A Instrument Controller using Fluke BASIC commands. Syntax may vary with the host.

INIT PORT 0<CR>

CLEAR PORT 0<CR>

PRINT @<address of meter>, "*IDN?"<CR>

INPUT LINE @<address of meter>, A$<CR>

PRINT A$<CR>
